diamond grinding stones

Diamond grinding stones contain small diamonds attached to the surface of a metal plate. These small industrial diamonds are much harder than any of the other grinding stones. However, not all diamond stones have the same function and they are not always equal.
There are two main types of diamond grinding stones.
1/ Diamond grinding stone with holes on the surface to catch metal chips.
2/ Diamond grinding stone with continuous surface. These stones are preferred for tools with sharp points that could get caught in the surface depressions of a non-continuous diamond grinding stone. Both types of diamond stones are available in monocrystalline and polycrystalline variants. Monocrystalline diamonds are more desirable because they last longer. The two biggest advantages of a diamond stone are very fast sharpening and flatness that is consistent. The disadvantage is the high purchase price.
